Description

Technical Field

[0001] This utility model relates to the field of polyester POY spinning technology, and in particular to a polyester POY spinning device based on ring blowing staged cooling. Background Technology

[0002] Polyester fiber, commonly known as "polyester," is a synthetic fiber made from organic diacids and diols through chemical polycondensation. It belongs to the category of polymer compounds. Its invention can be traced back to the 1930s, and it is now the most important type of synthetic fiber. During the spinning process of polyester POY, ring blowers are used to cool the fibers.

[0003] A search of the Chinese patent "POY Network Yarn Air Pressure Device for Thermal Insulation and Wear-Resistant Polyester Filament" (publication number CN211999996U) reveals that this patent connects one end of a blower pipe to a hole on one side of an annular air wall, and the other end of the blower pipe is connected to the output end of a fan. A fixing block is fixedly installed between the outer wall of the air cooler and the annular air wall. The annular air wall includes an inner annular air wall, and an outer annular air wall is fixedly installed inside the inner annular air wall. The surface of the outer annular air wall has multiple through holes, and grooves are formed at the same position on the outer walls of both the outer and inner annular air walls. This design solves the problems of traditional air pressure devices. The inability to uniformly cool chemical fiber products leads to defects and even damage in the finished products. The device uses a fan to blow cold air into the annular air wall through a connecting pipe, and then blows it out through the through holes on the outer wall of the annular air wall to cool and solidify the yarn blown out from the spinneret. However, the cooling of polyester POY yarn through the inner and outer walls of the annular air wall is not matched with the solidification stage of the yarn, which can easily lead to uneven cooling of the yarn, affecting the cooling effect of the yarn. It is also inconvenient to uniformly cool the yarn according to the solidification stage, thus reducing the effectiveness of the device.

[0004] Therefore, a polyester POY spinning device based on ring blowing staged cooling is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a polyester POY spinning device based on ring blowing and graded cooling to solve the above problems, thereby improving the problem of inconvenience in uniformly cooling the spun yarn according to its curing stage.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a polyester POY spinning device based on ring-blowing staged cooling, comprising a mounting box, the top of which is provided with a feeding trough; a cooling mechanism, which can perform staged cooling and fixation of polyester POY spinning, is disposed on the inner wall of the mounting box; wherein, the cooling mechanism includes several flow equalization plates evenly distributed and fixedly connected to the inner wall of the mounting box, and several evenly distributed rotating rings are rotatably connected to the inner wall of the mounting box, with mounting plates fixedly connected to both sides of the top of each rotating ring. The inner wall of the mounting plate is fixedly connected to a conduit, and one side of the conduit is connected to several evenly distributed nozzles. The rotating ring is located at the bottom of the flow equalization plate. A cooling component is provided on one side of the mounting box. The mounting box can be divided into three independent air chambers through multiple flow equalization plates, which can cool the polyester POY spinning at different stages and improve the processing quality of polyester POY spinning. The mounting plate at the top of the rotating rod sprays airflow through the conduit and nozzles to cool and solidify the polyester POY spinning, which can improve the quality of polyester POY spinning.

[0007] Preferably, the cooling mechanism further includes several evenly distributed and fixedly connected connecting rings, with the rotating ring rotatably connected to the top of the connecting ring. The inner wall of the connecting ring is fixedly connected to a conveying pipe, and one side of the conveying pipe is connected to a connecting pipe. The rotating ring is rotatably connected to the top of the connecting ring, so that the rotating ring can drive the mounting plate to rotate at a uniform speed, which can uniformly cool the polyester POY spinning.

[0008] Preferably, the outer wall of the rotating ring is fixedly connected with a plurality of evenly distributed tooth blocks, and a gear is provided on one side of the rotating ring. The rotating ring is connected to the gear through the tooth blocks, and the rotating ring can cooperate with the gear through the tooth blocks to make it rotate evenly.

[0009] Preferably, a rotating rod is rotatably connected to one side of the inner wall of the mounting box, and one end of the rotating rod is fixedly connected to several gears, so that the rotating rod can drive multiple gears to rotate simultaneously.

[0010] Preferably, a motor is installed at the bottom of the inner wall of the mounting box, and the output shaft of one end of the motor is fixedly connected to the rotating rod. The motor can drive the gear to rotate through the rotating rod.

[0011] Preferably, the cooling component includes several mounting blocks evenly arranged and fixedly connected to one side of the mounting box. A fan is installed on the inner wall of the mounting block, and a heating plate is installed at one end of the fan. The fan is a variable frequency fan, which can blow air when rotating. The airflow can uniformly cool the polyester POY spinning through the flow equalization pipe, and the temperature of the airflow can be controlled by the heating plate. The polyester POY spinning can be cooled at different stages through three air chambers.

[0012] Preferably, a filter screen is fixedly connected to one side of the mounting block, and the filter screen is located at the other end of the fan. The filter screen can intercept dust outside the device to prevent dust from affecting the fan and polyester POY spinning.

[0013] The beneficial effects of this utility model are:

[0014] 1. By setting up a cooling mechanism, the flow equalization plates inside the mounting box are evenly arranged, dividing the interior of the mounting box into three independent air chambers. This allows for different stages of cooling and solidification of polyester POY spinning, preventing uneven fiber structure in the polyester POY spinning. The rotating ring meshes with gears on the connecting ring through toothed blocks, which drives the two mounting plates on the rotating ring to rotate at a uniform speed. The connecting pipe and conveying pipe inside the connecting ring can transport the airflow into the duct, which is then sprayed onto the flow equalization plate by the nozzle. The annular flow equalization plate can evenly distribute the airflow, enabling uniform cooling of the polyester POY spinning and improving the processing quality of polyester POY spinning.

[0015] 2. By setting up a cooling component, when cooling and curing polyester POY spinning, the mounting block on one side of the mounting box generates airflow through the rotation of an internal fan. The airflow is delivered to the conveying pipe through the connecting pipe. The temperature of the heating plate can be controlled by the fan through the PLC control panel outside the mounting box. In conjunction with the fan, the upper air chamber can maintain mild cooling, the middle air chamber can be set to enhanced cooling, and the lower air chamber can maintain balanced cooling. The filter screen can prevent external dust from affecting the operation of the device, which can improve the processing quality of polyester POY spinning. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In practical implementation: such as Figure 1-4 As shown, a polyester POY spinning device based on ring blowing and graded cooling includes a mounting box 1 with a feed chute 2 at the top; a cooling mechanism 3, which can perform graded cooling and fixation of polyester POY spinning, is disposed on the inner wall of the mounting box 1; wherein, the cooling mechanism 3 includes several uniformly distributed flow equalization plates 301 fixedly connected to the inner wall of the mounting box 1, several uniformly distributed rotating rings 302 are rotatably connected to the inner wall of the mounting box 1, mounting plates 303 are fixedly connected to both sides of the top of the rotating rings 302, a conduit 304 is fixedly connected to the inner wall of the mounting plate 303, several uniformly distributed nozzles 305 are connected to one side of the conduit 304, the rotating rings 302 are disposed at the bottom end of the flow equalization plates 301, and a cooling component 313 is disposed on one side of the mounting box 1.

[0023] The mounting box 1 is installed below the spinneret. During operation, the melt is delivered to the spinneret for extrusion via a metering pump. The resulting nascent fibers enter the air chamber of the mounting box 1 through the feed chute 2 at the top of the mounting box 1. Moving from top to bottom, the fibers pass through three independent air chambers in sequence. The upper air chamber provides gentle cooling for the polyester POY spinning; the middle air chamber provides enhanced cooling; and the lower air chamber maintains balanced cooling for the polyester POY spinning. This stepped cooling mode allows the fibers to obtain the optimal heat dissipation curve in the glass transition range, improving the processing quality of polyester POY spinning.

[0024] like Figure 2 , Figure 3 and Figure 4As shown, the cooling mechanism 3 also includes several evenly distributed and fixedly connected connecting rings 306. A rotating ring 302 is rotatably connected to the top of the connecting rings 306. A conveying pipe 307 is fixedly connected to the inner wall of the connecting rings 306. A connecting pipe 308 is connected to one side of the conveying pipe 307. Several evenly distributed toothed blocks 309 are fixedly connected to the outer wall of the rotating ring 302. A gear 310 is provided on one side of the rotating ring 302. The rotating ring 302 is meshed with the gear 310 through the toothed blocks 309. A rotating rod 311 is rotatably connected to one side of the inner wall of the mounting box 1. One end of the rotating rod 311 is fixedly connected to several gears 310. A motor 312 is installed at the bottom. The output shaft of one end of the motor 312 is fixedly connected to the rotating rod 311. When the fan 3132 rotates, it can deliver gas to the nozzle 305 on one side of the duct 304 through the connecting pipe 308 and the conveying pipe 307. The gas sprayed from the nozzle 305 blows towards the flow equalization plate 301. The motor 312 drives the gear 310 on the rotating rod 311 to mesh with the tooth block 309, which drives the mounting plate 303 on the rotating ring 302 to rotate, so that the nozzle 305 can blow the gas evenly towards the flow equalization plate 301. The flow equalization plate 301 evenly distributes the gas and improves the cooling effect of the device on polyester POY spinning.

[0025] like Figure 2 and Figure 3 As shown, the cooling component 313 includes several mounting blocks 3131 evenly arranged and fixedly connected to one side of the mounting box 1. A fan 3132 is installed on the inner wall of the mounting block 3131. A heating plate 3133 is installed at one end of the fan 3132. A filter screen 3134 is fixedly connected to one side of the mounting block 3131. The filter screen 3134 is located at the other end of the fan 3132. The power of the heating plate 3133 and the fan 3132 in multiple air chambers can be adjusted through the PLC control panel, so that the upper air chamber maintains mild cooling, the middle air chamber is set to enhanced cooling, and the lower air chamber maintains balanced cooling. Different stages of cooling can be performed on polyester POY spinning to improve the processing quality of polyester POY spinning.

[0026] In use, the polyester POY yarn enters the mounting box 1 through the feed chute 2. The fan 3132 inside the drive mounting block 3131 rotates and blows air through the PLC control panel outside the mounting box 1. The airflow is delivered to the conveying pipe 307 via the connecting pipe 308. The conveying pipe 307, through the connecting ring 306 and the rotating ring 302, delivers the gas to the duct 304, where it is sprayed out by the nozzle 305. The gas is then blown onto the polyester POY yarn through the flow equalization plate 301 to cool it. The LC control panel supplies current of different frequencies to the heating plates 3133 in multiple air chambers, so that the heating plates 3133 have different temperatures. In conjunction with the fan 3132, it can cool the polyester POY spinning at different stages. The PLC control panel drives the motor 312 to drive the gear 310 on the rotating rod 311 to mesh with the tooth block 309, which can drive the rotating ring 302 to rotate. The rotating ring 302 drives the nozzle 305 in the mounting plate 303 to rotate at a uniform speed, which can uniformly cool the polyester POY spinning.

[0027] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
